Abstract: The present invention relates to a catalyst used in the manufacture of fatty acid alkyl esters and a method for preparing fatty acid alkyl esters using the same. The invention provides a high hardness solid ceramic metal catalyst obtained by mixing and sintering 0 wt %-80 wt % active catalyst material with a support material, wherein the support material is a silica alumina that is a mixed metal oxide and the active catalyst material is at least one of oxides, carbonates, and hydroxides of any kind selected from magnesium (Mg), calcium (Ca), zinc (Zn), titanium (Ti), manganese (Mn), vanadium (V), beryllium (Be), copper r (Cu), zirconium (Zr), strontium (Sr), tin (Sn), and barium (Ba). In addition, the invention provides a method for preparing fatty acid alkyl esters by performing transesterification and esterification of animal and vegetable oils and alcohols in the state where the ceramic metal catalyst is fixed within a reactor without processes for removing and purifying the catalyst.
